The easiest and safest way to convert you steem to hive - via Hive Engine

Bittrex and Binance are indefinitely disabled.
Poloniex is open but is never safe to use. #jsunthing
Ionomy is also open but will take time to create an account.

But don't worry, there's one last option for your steem to converted/sold into/for hive, and that's with the help of Hive-engine.

In this 3-min video that will guide you on how to convert your tokens, you'll just have to visit a single site without directing yourself into other websites. But you need to have the following wallet apps for your operation.

• Hive Keychain
• Steem Keychain

1. Login to hive-engine
2. Deposit steem, take note the account name and memo to be used
3. Use steem keychain and send your steem to the account given and memo
4. Trade your swap.steem to hivep
5. Withdraw hivep
6. Use hive keychain to withdraw your hive to your hive account.

Every operation takes a few seconds and delay in reflecting into your wallet balance. Just do some page refresh every now and then.

I hope it helps.
